The MB-800 is the one exam behind the Microsoft Certified: Dynamics 365 Business Central Functional Consultant Associate certification. You get 100 minutes, you need a score of 700 out of 1,000, and the exam costs $165 in the United States. Microsoft rewrote the skills outline on June 30, 2026, so study notes made before that date no longer match the exam.
Every figure in this post was read on Microsoft Learn on 14 October 2026. Prices and outlines change, so check them again before you book.
What is the MB-800 exam, and who is it for?
MB-800 tests whether you can set up and run Dynamics 365 Business Central for a small or medium business. Microsoft rates the certification Intermediate and lists the job role as Functional Consultant.
On its Business Central Functional Consultant Associate page, Microsoft describes the candidate as someone who configures the core application, creates companies, migrates data and works with an implementation team. The modules it names are financial management, sales, purchasing, inventory and fixed assets.
Two more lines in that profile are easy to skip. Candidates are expected to configure role centers and to expand the product with extensions. They are also expected to configure and use Copilot capabilities in Business Central, including built-in agents.
What changed in the MB-800 skills outline on June 30, 2026?
Microsoft's study guide now lists the skills measured as of June 30, 2026, and it ends with a change log that compares the new outline with the old one. Three of the four skill areas appear in that log.
The MB-800 study guide records these changes:
- Set up Business Central: its share of the exam decreased. Inside it, "Set up core functionality" is marked as a major change, and the group "Describe Business Central integrations with other products" was removed.
- Configure financials: no change in its share. The sub-groups in the log (chart of accounts, posting groups, journals and bank accounts, accounts receivables, fixed assets) are all marked minor.
- Perform Business Central operations: its share increased. "Perform basic tasks in Business Central" is marked major. "Process payments and journals" became "Process journals and payments" and is also marked major. "Process inventory transactions" is new.
The fourth area, Configure sales and purchasing, is not listed in the change log.
The log gives the direction of each change and not the old numbers, so this post quotes no earlier percentages. What the log does show is where older notes are most likely to be out of date: core setup, basic tasks, journals and payments, and inventory transactions.
How are the four skill areas weighted now?
Two areas carry most of the exam. Configure financials and Perform Business Central operations are each 30 to 35 percent, so together they make up 60 to 70 percent (our addition, not Microsoft's wording).
- Set up Business Central: 20-25%
- Configure financials: 30-35%
- Configure sales and purchasing: 10-15%
- Perform Business Central operations: 30-35%
Microsoft publishes ranges, not exact figures, and it does not say how many questions come from each area. Our reading of the ranges is simple: an hour spent on posting groups or on posting a purchase invoice covers more of the exam than an hour spent on price lists.
What does each skill area ask you to do?
Each area is a list of tasks, and most lines begin with a verb such as set up, configure, create or process. Here is the short version.
- Set up Business Central. Create and configure a company, manage security with permission sets and security groups, set up number series, job queues and report layouts, enable Copilot and agent capabilities, set up dimensions, and manage approvals with workflows.
- Configure financials. General ledger setup, accounting periods, the chart of accounts, posting groups, journals and bank accounts, accounts payables and receivables, and fixed assets.
- Configure sales and purchasing. Inventory setup, items and locations, costing methods, customer and vendor master data, and prices and discounts.
- Perform Business Central operations. Basic tasks such as applying filters, personalizing pages, Edit in Excel and data analysis mode. Then purchases, sales, financial documents, journals and payments, fixed asset transactions and inventory transactions.
If you want every line of the outline in one place, EduSum's Business Central Functional Consultant exam syllabus sets the four areas out in a table, with the exam summary above it.
How is the MB-800 exam delivered?
MB-800 is a proctored exam booked through Pearson VUE, with 100 minutes to answer. For exams of this length Microsoft lists a seat time of 120 minutes, which also covers the instructions and the candidate agreement.
Microsoft does not publish a question count for MB-800. Its page on exam duration and exam experience says most certification exams contain between 40 and 60 questions and that the number can vary. The same page sets three rules that affect how you use the clock:
- You may take a break without asking in advance, but the exam clock keeps running while you are away.
- After a break you cannot go back to the questions you saw before it, even the ones you left unanswered.
- On associate exams you can open Microsoft Learn in a split screen beside the question. No extra time is added for it.
The exam is offered in eight languages: English, Japanese, Chinese (Simplified), German, French, Spanish, Portuguese (Brazil) and Arabic (Saudi Arabia). Microsoft updates the English version first and says the localized versions follow about eight weeks later.
Question types are not announced for a single exam. The certification page says only that you may have interactive components to complete, and it links an exam sandbox where you can try the question types in the real interface.
What score do you need, and what does MB-800 cost?
You need 700 or more on a scale of 1 to 1,000. Microsoft calls this a scaled score and warns that it may not equal 70 percent of the points.
Three scoring facts help on exam day:
- There is no penalty for guessing, so answer every question.
- Some questions may be unscored, and you are not told which ones.
- Results usually arrive within minutes, with a bar chart of your performance in each skill area.
The price shown for the United States is $165. Microsoft sets the price by the country or region where the exam is proctored, so pick your own country in the list on the certification page.
If you fail, you can retake the exam after 24 hours. From the second failure on, the wait is 14 days between attempts, with a limit of five attempts in 12 months. Microsoft says you must pay for a retake where a fee applies.
How do you read a Microsoft skills outline?
Read it as a task list with weights. The percentage tells you how much of the exam an area takes, and each bullet under it is something you should be able to do in the product.
EduSum's YouTube channel has no MB-800 video yet. The one below was made for AZ-104, Microsoft's Azure Administrator exam, not for MB-800. It walks through that exam's format, time limit, passing score and weighted skill areas, and the same way of reading an outline applies here.
How should you prepare after the update?
Start with the parts of the outline that changed, then spend your hours in proportion to the weights. One way to order the work (our suggestion):
- Print the current skills outline and mark every line "weekly", "have done it" or "never".
- Take the items the change log marks major or new first: core setup with Copilot and agents, basic tasks, journals and payments, and inventory transactions.
- Do the tasks in Business Central itself. The outline is written as actions, and reading about a posting group is not the same as setting one up.
- Take Microsoft's free practice assessment on Microsoft Learn, and open the exam sandbox once so the interface is not new on the day.
- Review your misses by skill area, because that is how the score report is laid out.
For a first look at how a Business Central task turns into a multiple-choice question, EduSum has ten MB-800 sample questions with an answer key. They are practice items written for study, not questions from the real exam.
If you prefer a class, Microsoft lists course MB-800T00-A, a five-day instructor-led course, and it offers self-paced study for the same material.
How do you keep the certification after you pass?
The certification has a 12-month renewal cycle, and renewing it is free. Microsoft's associate certifications expire every year unless you pass an online renewal assessment on Microsoft Learn.
The rules on Microsoft's certification renewal page are short:
- The assessment is free, unproctored and open book.
- You can take it at any time in the six months before the certification expires.
- A pass extends the certification by one year from its expiration date.
- You can try as many times as you need, as long as you pass before the expiry date.
So if you renew on time, the exam fee is paid once. Staying certified costs study time each year, not another exam.
